Stack is great until it's not. Don't let it be your only card. I was in Taiwan and couldn't load the card as they were having trouble with their Interac processor. Luckily I have a UK Monzo card that kind of saved the day for ATM transfers. My Canadian bank charge a stupid amount on ATM withdrawals.
